[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] In view of the problems mentioned in the above background technology, an embodiment of the present invention provides a torsion balance maintaining device for cable armor layer production to solve the above technical problems, and its technical solution is as follows:

[0025] See also Figure 1-Figure 5 .

[0026] A torsion balance maintaining device for cable armor layer production, comprising:

[0027] The armoring machine distribution plate 100, the circumferential edge of the armoring machine distribution plate 100 is provided with a plurality of trapezoidal groove threading holes 110;

[0028] A guide mechanism 200 is provided at the front side of the armoring machine distribution plate 100 at the position of each trapezoidal groove threading hole 110;

[0029] The guide mechanism 200 includes a distribution plate 210 vertically fixed on the armoring machine distribution plate 100, and a first guide wheel 230, a second guide wheel 220 and a third guide wheel 240 sequentially connected to the distribution plate 210; the second guide wheel 220 is provided with an annular trapezoidal groove 221 along its circumference.

[0030] The telescopic cylinder mechanism comprises a first telescopic cylinder 310 and a second telescopic cylinder 320;

[0031] The second telescopic cylinder 320 is fixed on the rear side of the armoring machine distribution disk 100, and the first telescopic cylinder 310 is fixed on the process position of the armoring machine adjacent to the armoring machine distribution disk 100; the second telescopic cylinder 320 is embedded on the outer surface of the first telescopic cylinder 310 and the first telescopic cylinder 310 and the second telescopic cylinder 320 are locked by screws.

[0032] The first guide wheel 230 is responsible for guiding the armored steel wire into the guide mechanism 200, ensuring that the steel wire can smoothly pass through each guide wheel;

[0033] The second guide wheel 220 is provided with a trapezoidal groove 221 in its circumference, which can effectively grasp the armored steel wire and form a certain pressure on it, so that the steel wire moves along a preset trajectory and prevents it from deviating or "turning over" during the movement;

[0034] The third guide wheel 240 continues to guide the armored steel wire so that it finally smoothly enters other process parts of the armoring machine.

[0035] The combination and structural arrangement of the guide wheels on the guide mechanism 200 allow the entering armored steel wire to form a W-shaped path in the guide mechanism 200. This path locks the movement trajectory of the armored steel wire and prevents the armored steel wire from "turning over" during movement. In addition, the structural design of the guide mechanism 200 makes the stress on the passing armored steel wire more uniform during the forming process, thereby reducing the generation of internal stress and reducing the torsional imbalance caused by uneven tension.

[0036] With the help of the telescopic tube mechanism, the tension of the armored steel wire before entering the guide mechanism 200 can be optimized and adjusted; reasonable tension can prevent the "turning over" phenomenon of the steel wire during the forming process, ensuring the uniformity and reliability of the armor layer.

[0037] In this embodiment, the first guide wheel 230, the second guide wheel 220, and the third guide wheel 240 are arranged in a herringbone shape; the second guide wheel 220 is located in the middle; the design of the first, second, and third guide wheels being arranged in a herringbone shape can effectively guide the armored steel wire to form a relatively fixed motion trajectory and reduce instability during movement.

[0038] In this embodiment, the first guide wheel 230 and the second guide wheel 220 are both circular guide wheels.

[0039] In this embodiment, a threaded hole 321 is provided on the second telescopic tube 320 , and a screw is inserted into the threaded hole 321 to lock the first telescopic tube 310 and the second telescopic tube 320 .

[0040] The working method of a torsion balance maintaining device for cable armor layer production provided by an embodiment of the present invention is as follows:

[0041] 1. First, adjust the translational sliding position of the second telescopic cylinder 320 on the first telescopic cylinder 310, adjust and control the distance between the armoring machine distribution plate 100 and the adjacent process part (pressing structure) in front of it, and optimize the telescopic cylinder mechanism to better optimize and eliminate the tension of the armored steel wire during the forming process; when the second telescopic cylinder 320 reaches the appropriate position, fix it with screws;

[0042] 2. When the armored steel wire reaches the armoring machine distribution plate 100, the armored steel wire first passes through the trapezoidal groove threading hole 110 of the armoring machine distribution plate 100, and then enters the guide mechanism 200. In the guide mechanism 200, it first passes through the first guide wheel 230, and then is stuck in the trapezoidal groove 221 of the second guide wheel 220, and then passes through the third guide wheel 240 and is led out and then enters other process structures of the armoring machine; the cooperation of the guide wheels in the above-mentioned guide mechanism 200 makes the armored steel wire be extruded into a W shape and positioned, locks the movement trajectory of the armored steel wire, and makes the stress on the armored steel wire during the forming process more uniform;

[0043] 3. The present invention locks the movement trajectory of the armored steel wire through the cooperation of the telescopic tube mechanism and the guide mechanism, thereby preventing the armored steel wire from "turning over" during the movement; and eliminates the tensioning force of the armored steel wire before the guide mechanism, further preventing the steel wire armor layer from "turning over" during molding; at the same time, the cooperation of the above structures reduces the generation of internal stress of the armored steel wire, effectively improves the strength of the cable itself, and effectively improves the fatigue life of the armor layer that does not reach the designed life.

[0044] A torsional balance maintaining device for cable armor layer production provided by an embodiment of the present invention has the following beneficial effects: the present invention can reduce internal stress during the armor layer forming process by adjusting the tensioning force of the armor steel wire and limiting the movement trajectory of the armor steel wire, thereby effectively improving the overall strength and fatigue life of the cable and extending its service life.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
